Further Information

The Resource Manager for northern Victorian regulated water systems today announced an update to the seasonal determinations for 2013/14.

The Murray season determination has increased by 8% to be 50% high-reliability water shares (HRWS). Seasonal determinations in the Goulburn and Loddon systems are 72% HRWS, which is an increase of 18%. The seasonal determinations in the Campaspe, Broken and Bullarook systems are unchanged.

"Rain over the past fortnight has increased inflows to the storages across northern Victoria,” said Dr Mark Bailey, Resource Manager. “These inflows have allowed the increase in the Murray, Goulburn and Loddon seasonal determinations. The Murray Early Season Reserve for 2014/15 has now been fully established so all future resource improvements will contribute to increasing the seasonal determination."

Trading Opportunities

The probability of spill in the Victorian Murray system is currently greater than 50%. Therefore, trade into Victoria from New South Wales will be limited to the volume of trade out of Victoria to New South Wales. The availability of trade from NSW into the Victorian Murray system will be recalculated on 12 August 2013, and the 10th or next business day of each month thereafter. This limit is part of trade controls announced in November 2012 to prevent trade impacting on new season allocations.

Customers participating in the water trading market are reminded that the Murray-Darling Basin Authority has relaxed the rule controlling allocation trade from upstream of the Barmah Choke to downstream users. The Murray-Darling Basin Authority will regularly review the ability to trade across the Barmah Choke and may lift the relaxation at any time during the season.
